Answer 2

$\underline \bold{Solution:-}$

Cost of computer (P) = 21000 rupees

Time = 1 year

Rate of depreciation = 5 %

Amount

$= p {(1 - \frac{rate}{100}) }^{time} \\ \\ = 21000 {( 1-\frac{5}{100}) }^{1} \\ \\ = 21000 {( 95/100) }^{1} \\ \\ = 21000\times {0.95}^{1} \\ \\ =19950$

After 1 years it's cost will be 19950rupees.
